Abstract

The invention discloses a pump driven by a brushless direct current motor, a pump equipped with the brushless direct current motor as well as a manufacturing method of the brushless direct current motor for driving the pump. The brushless direct current motor of the pump comprises a motor shell and a motor shaft, wherein the motor shell comprises a lower end cover and an upper end cover, a statorpart is fixed between the lower end cover and the upper end cover, the motor shaft passes through the lower end cover and extends downwards, surrounding edges extending upwards are arranged at the periphery of the upper end cover, a circuit board chamber is arranged at the upper side of the upper end cover and is internally provided with a control circuit board and an encapsulating body made of encapsulating material, an internal lead of the control circuit board is connected with a connecting wire of the motor after passing through an internal lead hole on the upper end cover, and an external lead of the control circuit board passes through the encapsulating body and extends outwards. The control circuit board is sealed in the circuit board chamber in the way of encapsulating, and the encapsulating body can protect the control circuit board, ensure the reliability of motor control and operation, simplify the structure of the motor and facilitate the assembly of the motor.

Description

technical field [0001] The invention relates to a drainage pump for air conditioners, in particular to a motor of a DC brushless motor pump, and also relates to a method for manufacturing the DC brushless motor pump with the motor and the motor of the DC brushless motor pump. Background technique [0002] For ceiling-mounted air conditioners, how to drain the condensed water generated by the evaporator to the outside is an important issue for this type of air conditioner; therefore, ceiling-mounted air conditioners are generally equipped with a drain pump and a water tray; the water tray is used to collect condensation Water, the suction port of the drain pump is used to suck the condensed water collected in the water tray, and discharge it to the outside or other predetermined locations through predetermined pipes. [0003] The use environment of the ceiling air conditioner puts forward high requirements on the working performance of the drainage pump. On the one hand, the ...
